Answers

Preventive maintenance involves taking measures to help keep the system functioning, whereas corrective maintenance involves the replacement or repair of a system or its components after they have already failed
Answer:
Keyboard
The crumbs, dust, and other particulate that fall between the keys and build up underneath are loosened by spraying pressurized air into the keyboard, then removed with a low-pressure vacuum cleaner. A plastic-cleaning agent applied to the surface of the keys with a cloth is used to remove the accumulation of oil and dirt from repeated contact with a user's fingertips. If this is not sufficient for a more severely dirty keyboard, keys are physically removed for more focused individual cleaning, or for better access to the area beneath. Finally, the surface is wiped with a disinfectant.
Monitor
A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures and It’s a part of Output Devices.
Mouse
The top surface of the mouse is wiped with a plastic cleanser to remove the dirt that accumulates from contact with the hand, as on the keyboard. The bottom surface is also cleaned to ensure that it can slide freely. If it is a mechanical mouse, the trackball is taken out, not only to clean the ball itself, but to scrape dirt from the runners that sense the ball's movement and can become jittery or stuck if impeded by grime.
Tower/desktop unit
Internal components accumulate dust brought in by the airflow maintained by fans to keep the PC from overheating. A soft brush may remove loose dirt; the remainder is dislodged with compressed air and removed with a low-pressure vacuum. The case is wiped down with a cleaning agent. A pressurized blower or gas duster can remove dust that cannot be reached with a brush.
